General precautions
Protection Circuitry
The built-in amplifier incorporates
special protection circuitry which will
disable the amplifier if any of the
following should occur:
Before installing and using your new
amplified subwoofer, please
become familiar with all the infor-
mation contained in this manual.
• Input overload
Please keep this manual in a safe
place for future reference.
• Short circuit
• Do not open or attempt to repair this
unit yourself. Dangerous high voltages
are present which may result in electric
shock. Refer any repairs to a qualified
service technician.
• Extremely high temperatures
If any of these conditions is detected,
the amplifier will go into a self-
preservation mode, and the PROTECT
LED on the control panel will glow in
RED color.
• To avoid risk of electronic shock or
damage to the unit, do not permit any
of this equipment to become damp or
wet from water or drinks. If this does
occur, immediately unplug the power
wires and send the product to your
local dealer or service center as soon
as possible.
What should I do if the POWER STATUS
LED turns RED?
If you observe that the POWER STATUS
LED IS RED, please check the system
carefully to determine what has caused
the protection circuit to engage.
• If there is smoke or any peculiar odor
present during use or if there is damage
to any of the component enclosures,
immediately unplug the power cord
and send the product to your local
dealer or service center as soon as
possible .
To reset the amplified subwoofer when
it is in PROTECT mode, turn the power
off to the system (usually by turning off
the head unit or other signal source
which feeds the amplifier) and then turn
it on again.
If the internal amplifier has shut down
due to thermal overload, you should first
allow it to cool down before restarting.
SHOCK HAZARD! Do not open the case
of this product. There are dangerous
voltages present within the unit. There are
no user-serviceable parts within the unit.
If the shut down was due to either an
input overload or a short circuit, be sure
to correct these conditions before
attempting to power up the subwoofer
again.

Installation precautions
Mounting the subwoofer
Before you drill or cut any holes,
investigate your car's layout very
carefully. Take special care when you
work near the gas tank, fuel lines,
hydraulic lines and electrical wiring.
1. Find a suitable location in the vehicle
in which to mount the amplifier. Since
the subwoofer is a large, heavy
enclosure, it is highly recommended
that you mount it in the trunk
compartment of your vehicle.
Never operate the subwoofer when it
is unmounted. Attach all audio system
components securely within the
amplifier to prevent damage, especially
in an accident.
2. Make sure there is sufficient air
circulation around the intended
mounting location.
3. Mark the location for the mounting
hole screws by positioning the cabinet
where you wish to install it. Use heavy
duty bolts to secure it. After you
tightened it down, try to shake it or
move it. Then tighten the screws again.
Do not mount this product so that wire
connections are unprotected, in a
pinched condition, in contact with any
metal surfaces in your vehicle, or likely
to be damaged by nearby objects.
Before making or breaking power
connections in your system,
Connecting the subwoofer
Before doing any wiring, look through
this manual and identify the diagrams
to follow for power, input and speaker
connections for your particular
disconnect the vehicle battery. Confirm
that your head unit or other equipment
is turned off while connecting the input
jacks and speaker terminals.
installation. Be sure you understand
all the connections before you proceed.
If you need to replace the power fuse,
replace it only with a fuse identical to
that supplied with the product. Using
a fuse of a different type or rating may
result in damage to your audio system
or your amplifier which isnot covered
by the manufacturer's warranty.
1. Connect the ground terminal to the
closest point on the chassis of the
vehicle. Keep this ground wire to less
than 39" (100 cm) in length. Use 8
gauge (or heavier) wire.
Fuses
2. Connect the remote terminal to the
remote output of the head unit using
16 gauge (or heavier) wire.
Power fuses protect both the amplifier
and the electrical system of your car
from fault conditions. If you must
replace a fuse in your BASS1000
powered subwoofer, use a fuse of
exactly the same type and rating. Using
a different type or rating of fuse may
result in damage to your amp or vehicle
or cause a fire.
3. Connect an empty fuse holder within
18" (45 cm) of the car battery, and run
8 gauge (or heavier) cable from this
fuse to the amplifier location.
4. Check that the fuse holder is empty.
Then connect the fuse holder to the
"BATT+" connection on the amplifier.
BASS1000 Amplified Subwoofer User’s Manual - page 4
Don't misuse the
level control!
Do not mistake the input level control
for a volume control! It is designed
ONLY to match the output level of
your audio source to the input level
of your subwoofer.
6. Connect all line inputs and outputs (if
used) using high-quality cables. Connect
all speakers, following the diagrams in
this manual. Be sure to observe proper
polarity to avoid audio phase problems.
7. Insert fuse(s) into the battery fuse
holder(s).
Do not adjust this input level to
maximum unless your input level
requires it.
8. Recheck all connections before
powering up the subwoofer.
Ignoring these instructions will result
in an input overload to the amplifier
in the subwoofer, and excessive
audio distortion. It can also cause
the protection circuit to engage.
9. Set all level controls to minimum
position, and set all crossover
controls/switches to the desired
frequency points.
10. Power up the head unit and the
subwoofer. Then set the volume control
on the head unit to about 3/4 volume,
and adjust the subwoofer's input level
controls to just below the level of
distortion.
11. Further fine tuning of the various
controls may be necessary to obtain best
results.

INPUT GAIN CONTROL
After you have installed your system,
turn this control to minimum
different distance from the listener
than the other speakers in the system.
Turn the head unit on (and the
subwoofer will turn on via the remote
connection). Turn the head unit
volume to about 2/3 full level.
LOW PASS FILTER

Slowly turn up the subwoofer input
gain control until you hear a small
amount of distortion. Then reduce the
level until the distortion is completely
gone. Leave the control at this setting.
This control permits you define the
frequency range you want the
subwoofer amplifier to receive. The
subwoofer will reproduce all sound
BELOW the frequency you set.
If the rest of your system is weak on
the mids, you may wish to set this
control relatively high. If the midrange
is well covered by the rest of your
system, you will probably want the
subwoofer to only receive lower
frequency signal.
FUSE
6
The fuse in the upper socket is the
fuse which provides protection for the
circuitry. The fuse is rated at 25A. Do
not use a fuse with a different value
and NEVER replace the fuse with a
wire or coin.

HIGH LEVEL (speaker level)
INPUTS
If your head unit does not have RCA
outputs, you can use the speaker
outputs for the audio source for the
BASS1000. Use the supplied cable
and wire harness and connect the
outputs properly as shown in the
connection diagram in this manual.
LOW LEVEL RCA INPUTS
Low level inputs are the
10
recommended way to introduce the
audio signal to the subwoofer if RCA
outputs are present on your head unit
or other signal source (such as a
sound processor).
BASS1000 Amplified Subwoofer User’s Manual - page 7
Low Level Input Wiring
Low-level (RCA) input wiring is preferred for best audio performance. Most trunk
or hatchback installations will require a 15-20 foot RCA cable, while pickup trucks
and under-seat installations will require a 6-12 foot RCA cable. Always use a high-
quality cable.
NOTE: Do not connect BOTH the high level and low level inputs from your
receiver to your amplifier at the same time!

Troubleshooting
If you experience operation or performance problems with this product, compare your
installation with the electrical wiring diagram on the previous pages. If problems persist,
read the following troubleshooting tips which may help eliminate the problems.
SYMPTOM
POSSIBLE REMEDY
Check to make sure you have a good ground connection.
Check that the Remote Input (Turn-On) has at least 3VDC.
Check that there is battery power on the (+) terminal.
Check that there is at least 12v.
Amplifier will not
power up.
Check all fuses, replace if necessary.
Make sure that the Protection LED is not illuminated. If it is lit, shut off
the amplifier briefly, and then repower it.
Check for short circuits on speaker leads.

powered up.
Check that all fuses are OK.
No output.
Check that unit is properly grounded.
Check that the Remote Input (Turn-On) has at least 3VDC.
Check that the RCA audio cables are plugged into the proper inputs.
Check all speaker wiring.
Reset the Level Control.
Low output.
Check the Crossover Control settings.
Disconnect all RCA inputs to the power sub’s control panel. If the hiss
disappears, then plug in the component driving the amplifier and unplug
its inputs. If the hiss disappears at this point, go on until the faulty/noisy
component is found.
High hiss in the
sound.
It is best to set the amplifier's input level control as low as possible. The
best subjective signal-to-noise ratio is achieved in this manner. Try to
set the head unit as high as possible (without distortion) and the amp
input level as low as possible.
Check for improperly grounded RCA interconnects.
Squealing noise
is present.
Check that the Input Level Control is set to match the signal level of the
head unit. Always try to set the Input Level as low as possible.
Distorted sound.
Check that all crossover frequencies are properly set.
Check for short circuits on the speaker leads.
Check that the minimum speaker impedance for the amp model is correct.
Amplifier gets
very hot.
Check that there is good air circulation around the amp. In some
applications, it may be necessary to add and external cooling fan.
This is usually caused by poor quality RCA cables,which can pick up
radiated noise. Use only the best quality cables, and route them away
from power cables.
Engine noise
(static type)
Check that the RCA grounds are not shorted to the vehicle chassis.
Check that the head unit is properly grounded.
